This is achieved by means of a Venturi constriction in the flow path of the gas in the pipe (1), as well as a flow cone (4 a) positioned on a push rod (4) that is disposed centrally, whereby a connecting rod system (4 b) that is guided to the outside is provided to move the push rod (4), whereby the connecting rod system (4 b) that moves the push rod (4) is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector (8) by way of a packed gland (6).

Description

CROSS REFERENCE TO RELATED APPLICATIONS
This application is the National Stage of PCT/EP2010/002417 filed on Apr. 21, 2010, which claims priority under 35 U.S.C. §119 of German Application No. 10 2009 022 186.7 filed on May 20, 2009, the disclosure of which is incorporated by reference. The international application under PCT article 21(2) was not published in English.
The invention is directed at a device for influencing the flow in a horizontal connecting pipe between a coal gasification reactor and a gas cooler/purifier.
A production possibility for synthesis gas consists in the gasification of finely ground fuels that contain carbon, with a gas that contains oxygen. In this connection, a gaseous product is obtained, which consists essentially of carbon monoxide. When steam is mixed into the starting gas, a product gas is obtained that also contains hydrogen as an admixture. The synthesis gas obtained in this manner is suitable for the production of ammonia or methanol, for example, but also for making hydrogen available.
In the production of synthesis gas by means of a coal gasification process, a coal gasification reactor is used, which yields a synthesis gas charged with solids and acidic gases. For further use, this gas must be purified, so that it is passed into a device for gas scrubbing. In order to be able to control the gas stream from the reactor into the device for gas scrubbing, it is necessary to interrupt or regulate the gas stream.
However, regulation with conventional valves or slides frequently requires maintenance or is subject to break-down, because the synthesis gas is hot and can be charged with corrosive components. Conventional valves or slides must therefore be replaced after some time, and this leads to increased operating costs and increased maintenance effort.
This is where the invention takes its start; its task consists in being able to reduce or shut off the gas stream of a hot synthesis gas, if necessary, without being exposed to the high stresses caused by the corrosiveness and the high temperatures, while avoiding complicated valves or regulation devices.
This task is accomplished with a device of the type indicated initially, by means of a Venturi constriction in the flow path of the gas in the pipe, as well as a flow cone positioned on a push rod that is guided centrally, whereby a connecting rod system that is guided to the outside is provided to move the push rod, whereby the connecting rod system that moves the push rod is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector by way of a packed gland.
By means of the invention, an optimal regulation possibility is made available, using simple means, within a horizontal connecting pipe between the coal gasification reactor, on the one hand, and a gas scrubber, on the other hand.
At this point, it should be noted that a high-performance wet precipitator is known from DE 21 50 015 A, for example, which is formed by a pipe in which a flow cone sits to produce a Venturi effect, whereby this cone is slightly adjustable longitudinally, in order to be able to adjust the flow speed and the throughput in the pipe; here, a longitudinal displacement device that can be activated from the outside is not provided, nor are any special measures for temperature stabilization.
In the literature, a number of solutions are known, in which installations are provided in flow paths, which serve to regulate the flow, particularly also to block off the flow path, whereby Venturi-like elements are provided, which are installed, with some exceptions, not in the horizontal direction, as shown in U.S. Pat. No. 3,839,185, but rather in the vertical direction. DE 199 52 754 A1, DE 18 76 032 U, AT 267 479 B, U.S. Pat. No. 3,517,485, U.S. Pat. No. 3,638,925, U.S. Pat. No. 3,690,044, or U.S. Pat. No. 4,167,401 are mentioned as examples.
Embodiments of the invention are evident from the dependent claims. In this connection, it can be provided that the push rod is provided with a setting device, whereby it is practical if the connecting rod arm that impacts the push rod, which lies on the inside and is guided to the outside, interacts with such a setting device.
In a further embodiment, it is provided, according to the invention, that the setting device is configured for mechanical and/or electrical and/or hydraulic adjustment of the push rod.
It can be practical, as the invention also provides in a further embodiment, that at least two dummy connectors, particularly three dummy connectors having connecting rod arms that impact the push rod are provided, and that particularly great stability and functional reliability are guaranteed by means of the three-arm configuration.
Another practical embodiment of the invention consists in that water injectors are provided in the flow path of the gas in the pipe, ahead of the Venturi constriction.
Depending on the type of construction, it can be advantageous to configure part of these water injectors as support elements for the push rod, at the same time.
In order to deal with the stresses that occur, the invention also provides, in a further embodiment, that at least the elements and surfaces that stand in contact with the gas that flows through consist of a corrosion-resistant material or are provided with a corrosion-resistant coating.
This embodiment is advantageous, because synthesis gas that is produced can have temperatures of 200° to 1700° C., whereby the pressures of the synthesis gas can amount to between 0.1 to 30 MPa, whereby this numerical information serves only as an example, without the invention being restricted to this.
Further details, characteristics, and advantages of the invention are evident from the following description and from the drawing. This shows, in
FIG. 1 in a simplified representation, the connecting pipe according to the invention, with the device in section, with the flow cone in the closed position,
FIG. 2 in a similar representation, the flow cone in the open position,
FIG. 3 a cross-section through a pipe equipped with a device according to the invention, having three setting devices, as well as in
FIG. 4 in the representation of FIG. 2, the device according to the invention with water injection.
FIG. 1 shows a connecting pipe 1 through which a gas stream 2 is guided, proceeding from a coal gasification reactor. The gas stream must pass through a constriction 3 as it is guided through the pipe. This constriction is blocked off by means of a push rod 4 having a flow cone in the form of a thickened region 4 a. The guide rod is passed to the outside by way of a connecting rod system 4 b having two nodes 5 a, 5 b, through a packed gland 6, and driven by a setting device in the form of an actuator motor 7 there. The connecting rod 4 b is guided by a dummy connector 8 that is blocked off with a closure lid 8 a. The gas stream 9 exits at the end of the connecting piece, where a device for gas scrubbing follows.
FIG. 2 shows a connecting pipe 1 through which a gas stream 2 is guided, proceeding from a coal gasification reactor. The gas stream 2 must pass through a constriction 3 as it is guided through the pipe. A push rod 4 having a flow cone in the form of a thickened region 4 a, which is retracted here, leads through the pipe. As a result, the pipe is passable for the gas stream.
FIG. 3 shows the connecting pipe 1 in the frontal view. The pipe is constricted, in cross-section, by means of a constriction 3, with which the velocity of the gas stream is increased. A flow cone in the form of a thickened region 4 a, which is permeable for part of the gas stream 4 c here, is guided through the constriction. The thickened region is affixed to a push rod 4 that is connected with a setting device in the form of an actuator motor 7 by way of a connecting rod system 4 b. The connecting rod is guided in a dummy connector 8 by way of a packed gland 6. Here, the closure lid 8 a can also be seen.
FIG. 4 shows the connecting pipe according to the invention with water injection devices. One of them is directed backward 10 a in the gas stream, and another is directed forward 10 b. Here, a device for venting the packed gland 11 can also be seen. Here, the device is in the open position.
